It's really just a red hoodie found at Target with the Robin symbol embroidered on the breast and the yellow bars along the zipper with the sleeves hemmed off. You could also do the same thing with felt (it's super cheap and awesome!) and fabric glue. Or if you're interested in one, just shoot me a note and I'll let'cha know how you can get your hands on one without doin' any work. ;]

Hehe and thank you! It was a fun way to run around in something comfortable at a con while paying homage to my favorite character. <3
